Unlike [[KeyConstant|key constants]], Scancodes are keyboard layout-independent. For example the scancode "w" will be generated if the key in the same place as the "w" key on an American keyboard is pressed, no matter what the key is labelled or what the user's operating system settings are.
  
For example, the key located where "q" is on a U.S. keyboard has the scancode "q". When using a U.S. keyboard layout it produces the key "q", but when using a French keyboard layout it produces the key "a". French keyboards usually label the key as "a" rather than "q".

This function is not supported in earlier versions.

Gets the hardware scancode corresponding to the given key.

Unlike key constants, Scancodes are keyboard layout-independent. For example the scancode "w" will be generated if the key in the same place as the "w" key on an American keyboard is pressed, no matter what the key is labelled or what the user's operating system settings are.

Scancodes are useful for creating default controls that have the same physical locations on on all systems.
